Lacking the time, energy, or initiative to prepare anything better, Hollywood-based event planner Frankie Haines spent roughly 20 minutes last week organizing a ‘Bags of Ice’–themed celebrity birthday bash. “I figure it makes sense: Parties and bags of ice, those are two things that go together,” said Haines, describing his inspiration for the hastily created, half-million-dollar soiree, which will feature five massive columns of ice bags stacked throughout the space, ice bags leading up the driveway, and possibly an ice-bag sculpture centerpiece, “if there’s time.”

What’s the most out-there (or quickly slapped-together) theme you’ve ever used for an event?
